P0420 Code (1 Viewer)

I got it the other day.
Started the truck up when cold (found that in search)
and I can plainly see an exhaust leak in the flange
between the 2 cats. I'm just going to order the gasket
and replace it as that seems like the cheapest, 99% sure
solution.

Any other thoughts?

Thanks, my leak is so obvious,
I can't imagine it would be anything else.
